            This example demonstrates feature editing with snapping to a regular
            grid.  The map is configured with a <code>OpenLayers.Layer.PointGrid</code>
            layer and a <code>OpenLayers.Control.Snapping</code> agent.  For the
            best performance, the point grid layer should not made visible.
            Snapping still works with layers that are not visible.

            See the <a href="snap-grid.js" target="_blank">
            snap-grid.js source</a> to see how this is done.
